Table_1_Process Evaluation of an Online SUpport PRogram for Older Hearing Aid Users Delivered in a Cluster Randomized Controlled Trial.docx

Objectives: To evaluate the process of implementing a web-based support program (SUPR) for hearing aid users in the Dutch dispensing setting in order to allow interpretation of the randomized controlled trial's results (positive effects on hearing-aid related outcomes; no effects on psychosocial outcomes).
Design: Measures: context of implementation, recruitment, SUPR's: reach, implementation fidelity, dose delivered, dose received, satisfaction, and benefit. Data collection: quantitative and qualitative.
Study Sample: One hundred thirty-eight clients (mean age 68.1 years; 60% male) and 44 dispensers completed questionnaires. Five clients and 6 dispensers participated in interviews and focus groups.
Results: Clients and dispensers were generally satisfied with SUPR's usefulness. SUPR-videos were watched by 7–37% of the clients. Around half of the dispensers encouraged clients to watch them or informed them about SUPR. Some clients found the SUPR-materials suboptimal, and changes in personnel and limited dispenser-training were barriers acting on a contextual level.
Conclusions: This study identified several factors that contributed to the success of SUPR. Others factors, acting on various levels (e.g., intervention material, dispensers, and implementation context), were suboptimal and may explain the absent psychosocial effects. The identified factors are important to consider in further development of SUPR, and in other web-based support programs.

研究目标：评估荷兰助听器（hearing aid）验配场景下，面向助听器使用者的网页版支持项目（SUPR）的实施流程，以支撑对本次随机对照试验（randomized controlled trial）结果的解读——该试验在助听器相关结局指标上呈现积极效应，但对社会心理结局指标无显著影响。
研究设计：测评维度涵盖实施背景、招募情况、SUPR项目的覆盖范围、实施保真度、干预递送剂量、干预接收剂量、满意度与获益情况。数据采集采用定量与定性相结合的研究方法。
研究样本：共计138名助听器使用者（平均年龄68.1岁，男性占比60%）与44名助听器验配师完成了问卷调查；另有5名使用者与6名验配师参与了访谈及焦点小组讨论。
研究结果：助听器使用者与验配师总体上对SUPR项目的实用性表示满意。7%至37%的使用者观看了SUPR教学视频。约半数验配师会鼓励使用者观看相关视频，或向其介绍SUPR项目。部分使用者认为SUPR相关材料有待优化，人员变动与验配师培训不足则属于实施背景层面的阻碍因素。
研究结论：本研究明确了若干可助力SUPR项目成功实施的影响因素。另有部分因素分别作用于不同层面（如干预材料、验配师群体与实施背景），其表现欠佳，或可解释本次研究未观察到社会心理层面获益的原因。上述识别出的影响因素，对于SUPR项目的后续优化，以及其他同类网页版支持项目的开发均具有重要参考价值。
